Improving Rails Performance

Slow Rails applications annoy users and lose revenue. Use blistering speed to your advantage.

This video, with thoughtbot CTO Joe Ferris, shows you how to tune performance using a real world example. Starting with an action that takes 3 seconds to respond and performs over 1600 database queries, Joe is able to reduce response time to 300ms and drop database usage to just 5 queries.

In this 36 minute video, Joe demonstrates making these performance improvements without duplication, and without breaking your existing code.

This video specifically focuses on what Joe calls ‘real-time requests’. That is, requests that must return all of their data to the user in the request-response cycle, without relying on background jobs or persistent caching.

If you’d like to become a specialist in curing slow-app-itis, this video is for you!
